Here is one I logged earlier this year
Beautiful country reasonably easy find the altitude almost killed me. Parked by the gate, gps says 600 ft to cache struggled to climb the first embankment paused out of breath at top gps 595 ft to cache. Start towards the cache up up up till I can't walk for lack of breath so I take a break, gps 500 ft to go. Ok I catch my breath walk towards the cash again until I'm so out of breath I can hardly move sit down and take a break look at the gps man I must be close now............ gps says 400 feet. Crap I need to get in shape.
